In this video I demonstrate a Twist Drill Sharpening technique for beginners, that is quick, simple and highly accurate.
Step 1. Be aware of the correct angles of a sharp twist drill.
Step 2. Set up some guidelines on the bench grinder.
Step 3. Use the guidelines on the bench grinder to achieve the correct twist drill angles while sharpening.
Step 4. After sharpening check the twist drill point angle (120°) and relief angle (7-10°) and that the point is centrally located.
Step 5. Test the sharpened twist drill on a piece of metal or wood.
